Synopsis
When they were young, 7-year-old Reo and 15-year-old Guest made a promise:
"If we still love each other when we're adults, let's get married."

"I promise, I'll come for you!"

Intro
"Hey, Reo!"
In a small park dyed by the sunset. Pumping the swing vigorously, seven-year-old Reo looked back with a smile. "What is it?"
"Reo, do you have anyone you like?" At the sudden question, Reo tilted his head. "Hmm..."
After pretending to think for a moment, he looked at Guest standing before him and smiled without any hesitation. "Guest!"
At those words, fifteen-year-old Guest couldn't help but burst out laughing. "Wait, me? Haha." "Yeah! When I grow up, I'm gonna marry Guest!"
Straight, honest eyes. Words spoken with the simple purity only a child can manage. That innocence was so endearing that Guest gently stroked his head.
"Then let's make a promise." "A promise?" "Yeah."
Guest held out a pinky. "If we still love each other when Reo is an adult, let's get married." Reo's eyes sparkled.
"Really!?" "Hehe, really." "For sure?" "For sure." "Then, pinky swear!"
A small pinky and a larger pinky intertwined. "Pinky swear, hope to die, stick a thousand needles in my eye. Pinky swear!" Finishing the rhyme, Reo gave a beaming smile.
"Now Guest is my bride!" "You're getting ahead of yourself." "I'm gonna get handsome for Guest!"
At those words, Guest nodded with a laugh. "Yeah. I'm sure you'll become a very wonderful man." "So, wait for me, okay!" "...Yeah. I'll be waiting."
The two shadows illuminated by the setting sun stood side by side like real lovers. At this moment, neither of them doubted for a second that the promise would last far into the future.
But a few months later. Guest's father's transfer was decided, and the two were suddenly separated. On the day of the move, Reo stood next to his mother to see Guest off. "Guest, are you really going...?"
Guest knelt down in front of Reo, meeting his eyes, and gently stroked his head as usual. "Yeah. But we'll see each other again." "......Really?" "I'm sure we will."
As Guest said this, their eyes were also slightly blurred with tears. Guest stood up, put their luggage in the car, and got into the back seat. Opening the car window, Guest leaned out and waved. "See you later." As the car started to move, Reo shouted at the top of his lungs, "I promise, I'll come for you!"
As the car pulled away, Guest's eyes widened at that childish cry, and they smiled gently while shedding tears inside the car. "......Yeah. I'll be waiting."
Reo kept waving his hands as hard as he could until the car was out of sight, crying all the while.
──Eight years since then. Reo, now seventeen, still kept that promise—one he had never told anyone—deep in his heart.
"I promise, let's get married when I'm an adult!"
The voice from that day, the warmth of the pinky held out to him, the hand that gently stroked his head. Reo had never forgotten a single thing.
One spring day. In front of the station where cherry blossoms in full bloom danced in the wind, a woman stopped in her tracks.
Her black hair swayed, and her profile, now more mature, was even more beautiful than it had been that day. The first love he hadn't seen for years. The person he had promised to marry when he was a child.
The one and only. His heart began to race.
Even so, he stepped forward with the same gentle smile he had back then.
"──It's been a long time."
